1.  Pictorial review of mucopolysaccharidosis with emphasis on MRI features of brain and spine 
The British Journal of Radiology  2011;84(1001):469-477.
Mucopolysaccharidosis (MPS) is an inherited metabolic disorder of childhood, characterised by progressive multisystem involvement predominantly affecting the skeletal system leading to skeletal dysplasia. Mental retardation, neuropathy and cardiomyopathy may occur in the most severely affected patients, leading to progressive disability and death in their early third to fourth decades.
The purpose of this paper is to illustrate the typical imaging features of different types of MPS, in particular the MR features of the brain and spine in MPS, which are expected to be encountered by radiologists more frequently in their clinical practice as a result of prolonged life expectancy for those with MPS with recent advances in therapeutic interventions. The treatment options and outcomes for MPS patients are also briefly discussed.

2.  Clinical presentations and imaging findings of neuroblastoma beyond abdominal mass and a review of imaging algorithm 
The British Journal of Radiology  2011;84(997):81-91.
Neuroblastoma is one of the most common malignant neoplasms in childhood. The most common clinical presentation of this tumour is abdominal mass. However, affected children may have various clinical presentations as a result of disseminated metastatic disease or associated paraneoplastic syndromes at the time of diagnosis. In this article we have outlined the imaging findings in seven patients with “extra-abdominal” presentation of neuroblastoma and the pitfalls in making the correct diagnosis. The purpose of this pictorial review is to alert the general radiologist to the possible presentations of this common childhood malignancy to derive early detection and diagnosis.

3.  Atypical location of germinoma in basal ganglia in adolescents: radiological features and treatment outcomes 
The British Journal of Radiology  2010;83(987):261-267.
The objective of this work is to describe the imaging findings, clinical profile and treatment response in four Chinese adolescent patients presenting with ectopic germinoma arising from basal ganglia. The clinical presentation, treatment regimens and the imaging findings at presentation and after treatment were described upon retrospective review of four Chinese adolescent patients. CT of the brain showed mixed solid cystic mass lesions in three patients. In one patient, only ill-defined hyperdensity was noted in the affected basal ganglia. Correlative MRI brain studies showed similar findings of large solid cystic masses in three patients, whereas the fourth patient showed small hyperintensities on T2 weighted and fluid-attenuated inversion-recovery sequences. All lesions were confirmed to be germinomas on biopsy. Chemotherapy followed by radiotherapy was given to three patients. There was a dramatic response, with complete resolution of tumour bulk in two patients and >80% reduction in tumour bulk in one patient. Debulking surgery was performed in one subject who had received cranial radiotherapy; the last follow-up MRI showed no evidence of residual disease.
